No-Frills™ Heart templates
The heart templates come in 6 different sizes. They have been designed so that the actual template itself fits inside the size square that it is. ie: a 6" heart fits exactly to the edge of a 6" square. If you wanted a heart that once quilted sat nicely inside a 6" square then you would probably use the 4" heart template.
All templates are 1/4" thick acrylic. They come with a protective paper or plastic coating that just peels off leaving no residue. The picture shows one of the hearts with its protective covering still on.
Below is a short video showing how I like to stitch around a heart template and also another use for the top 'bumps' of the heart in a border.
